Description

Thin material adsorption rotary platform mechanism capable of realizing large and small suction partition Technical Field The invention relates to the technical field of workpiece carriers, in particular to a thin material adsorption rotary platform mechanism capable of realizing large and small suction partition. Background The workpiece carrier, as the name implies, is used for loading the product, and the product can be directly placed on the workpiece carrier or fixed on the workpiece carrier in a vacuum adsorption mode, and for ultra-thin profiles, such as ultra-thin screens or protective films applied to intelligent equipment, the ultra-thin profiles are usually fixed on an adsorption carrier in a vacuum adsorption mode so as to perform operations such as film tearing and the like. As the prior art, the suction force of each position of the suction area formed by the upper end surface of the conventionally used suction carrier is the same, and the problem is that when the suction force is too large, a plurality of salient points are easily formed at the position points of the bottom surface of the adsorbed and fixed ultrathin material, which are adsorbed and sucked by negative pressure, so that the quality of a product is influenced, and when the suction force is too small, the adsorbed and fixed ultrathin material is not easy to be stably adsorbed and fixed, so that the whole ultrathin material is easy to be taken away when the upper surface of the ultrathin material is torn. In addition, for the conventionally used adsorption carrier, when the ultra-thin section bar is fixed and transferred, the suction area formed by the upper end surface of the adsorption carrier is always required to be very flat, so that the ultra-thin section bar is not easy to be absorbed and deformed due to uneven local absorption force of the ultra-thin section bar caused by uneven absorption surface when the ultra-thin section bar is absorbed by the material taking manipulator. Meanwhile, for the conventionally used adsorption carrier, when the ultra-thin profile is fixed and is subjected to film tearing or transfer conveying, a driving member for driving the ultra-thin profile to rotate circumferentially is often arranged, and when the ultra-thin profile is further provided with a negative pressure suction member and a flatness leveling member, the driving member, the negative pressure suction member and the flatness leveling member are difficult to integrate and are arranged at the bottom of the used adsorption carrier, so that the driving member and the negative pressure suction member are usually arranged beside the corresponding adsorption carrier, the circumferential dimension of the whole device is greatly increased, and the device is inconvenient to fix in a narrow space for use. In this regard, the present inventors have combined experience, through intensive thought of problems encountered in work, turned through a great deal of scientific research data and literature, and gradually conceived and designed the present application through searching for new ones, so as to solve the relevant technical problems.
